ABSTRACT:
A method for reducing the hydrogen sulfide content of hydrocarbon-containing fluids and aqueous solutions through a two-stage injection procedure whereby a dilute solution of a scavenging agent is injected into a hydrogen sulfide-containing fluid, followed by equilibration and a second injection of dilute solution of scavenging agent to further reduce the hydrogen sulfide content of the treated fluid.
